OpenAI has lowered API prices for two GPT-5.6 models only three weeks after their launch. On Thursday, the company announced that GPT-5.6 Luna is now 80% cheaper and GPT-5.6 Terra is 20% cheaper, while the price for its main reasoning model, GPT-5.6 Sol, stays the same.
“Major price cuts today,” OpenAI CEO Sam Altman writes in a post on X published on Thursday. “We want to offer the best price/intelligence tradeoff at every level.”

Luna now costs $0.20 for a million input tokens and $1.20 for a million output tokens, down from $1 and $6. Terra is priced at $2 per million input tokens and $12 per million output tokens, reduced from $2.50 and $15. Sol’s price stays at $5 per million input tokens and $30 per million output tokens.
Developers using Luna do not need to change their processes, but their inference costs will go down. High-volume tasks will now be much cheaper to run, without requiring any code updates or model changes.

This timing is unusual because AI vendors usually keep prices steady for several months after launching a new model family. OpenAI cut prices less than a month after GPT-5.6 became available on July 9.
